Things to keep, things to do — one home for your everyday. Shimau is one place for the scattered stuff of daily life: notes, to-dos, links, and photos. Videos from social media, half-read articles, screenshots, passing thoughts — just toss them in. No folders. No tagging. No filing. ◆ Zero-effort saving Pick "Shimau" in the share menu — you don't even need to open the app. For quick thoughts, tap the center "+". Shimau tells links from notes automatically as you type. ◆ AI understands what you saved Links and screenshots get automatic summaries and tags. Screenshots become searchable through on-device text recognition. Notes you write yourself are never sent to AI. ◆ Find things the way you remember them "That ramen video from last week" — search in your own words and it shows up. ◆ To-dos live on sticky notes Stick a note on a box, peel it off when it's done. The small satisfaction of an empty box keeps you going. Checklist notes open in a focused to-do mode. ◆ A one-line daily journal Once a day, log your mood and a single line — and look back with a little bear at your side. History, calendar, and stats grow the longer you keep going. ◆ Make it your own Choose a theme — Cozy or Lovely Pink, plus Calm Blue and Mono with Pro — and dress up box covers with theme art, photos, or colors and emoji. ◆ Only deadlines, gently When a saved booking or coupon has a date, Shimau offers a reminder. Choose how it speaks up: quiet, standard, or strong. No other notifications, ever. ◆ On iPhone and on iPad On iPad the screen splits in two, so you can see the list and what's in it at once. It also works alongside other apps in Split View and Slide Over. ◆ You can take it with you Back up everything in one file, or export to Markdown or JSON. It's free. Being able to leave without losing anything is part of what makes a place worth putting things in. ◆ Private by design What you save stays on your device. Nothing is stored on our servers or used to train AI. If you turn on iCloud sync, it is kept in your own iCloud. Things to keep, things to do, and how today felt — all in one place you'll always find again. That's Shimau. ―――――― Shimau Pro (auto-renewable subscription) Includes iCloud sync and backup, Face ID lock, and extra themes. ・$1.99 per month, renewing monthly ・$14.99 per year, renewing yearly Your subscription renews automatically unless cancelled at least 24 hours before the end of the period.

Verdict
The clearest difference is update cadence: ReturnRadar at daily against Shimau's every 4 days. Shimau's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.
